This invention relates to a dust 'pufl and the method of making thesame.

A dust pufi' in order to serve most efii- 'ciently should have a veryresilient body, the parts of which should be so interlocked that theywill not become disengaged readily and form separated bunches or'lumpswhich do not cooperate with each other. A good dust pufi also should befree from the tendency to harden and become incrusted when a cleaningoil is used with it in dusting and polishing.

The materials used in the making of this dust pufi" have been soselected and arranged that each of the above desirable qualities isincorporated in the resulting dust pu fi and other qualities peculiartothis invention are also found to be possessed by the dustpufl I madefrom this process.

One of the objects of this invention is to provide a dust pufi made offibrous material which naturally assumes and retains an ellipsoidalshape which is suitable for use in dusting.

Another object of this invention is to provide a dust mop which iscomposed of a plura-lity of strands of fibrous material and having bothends of each strand securely tied so that none of the ends may becomefree.

Another object of this invention is to provide a dust pufi' which iscomposed of strands of fibrous material and having both ends of eachstrand brought into a single knot where the ends are 'firmly securedinto a compact knot whichalso serves as a grip for the user.

Another object of this invention is to provide a dust pufl' made of manystrands of a fibrous material, each strand having previously been givena kinky form by means of knitting or some other suitable operation sothat the strands when laid in proximity to each other in many layerswill become considerably intermeshed and interlocked by means of theinterengagement of their kinky portions.

Another object of this invention is to provide a process for making adust pufi' which will produce a compact puff whosekinky strands are soWell intermeshed as to prevent.

the. puff from separating into disconnected bunches and yet which isassembled by a very simple arrangement of successive layers wound oneupon the other.

Another object of this invention is to provide a method of making a dustpufi' from kinky strands of fibrous material which fac'ilitates andcheapens the problem of tying the ends of the strands so that they maynot become loose and separated from the puff.

Another object of this invention'is to provide a method of making dustpuffs which utilizes kinky strands of fibrous material,

which strands may be prepared by knitting moval from the reel,

Fig. 8 shows another elevation of the dust pufi? taken at 90 to Fig. 2showing that the pufls are ellipsoids more closely resembling an egg inshape than the common circulartype of door knob,

Fig. 5 shows how. conveniently the'knot in the puff may be grasped whenthe puff is being used. I v

Referring in detail to the drawing, a knitted tubular piece 1 is held insome suitable relation to, the reel by means which is not shown 'norwhich is material to this invention. The strands are raveled from it asindicated and pass through a loop 2 mounted on a reciprocating bar 3which moves alternately to the right and to the left as indicated by thearrows. The group of strands after passing through the guide loop 2 arewound upon a simple reel having the separated rods 4. The apparatus forrotating the reel is not material to this invention and need not beshown. The reciprocation of the guide loop 2 will cause the groups ofstrands to be wound in successive layers which are crisscrossed. Thiscrisscrossing is employed in order to bring about the most effectiveintermingling of the kinky portions of the strands.

After a suflicient number of layers have been incorporated in the loop 5of the intermeshed material, the group 6 of strands is severed and theloop of wound material is removed from the reel. The loop of intermeshedstrands is now pinched together at its middle in a plane through theaxis of the loop and is tied-very firmly at the two separate points '4'and 8 which causes the outside portions of the loop of wound material tonaturally form into two ellipsoidal puffs 9 and 10.

After the two separated ties are completed a sharp knife cuts throughthe narrowed portion of the puff on the line 11-11 which results inproducing two puffs 9 and 10 each of which has a central button 12 inwhich both ends of each strand of the puif are securely tied. Not onlydoes the button 12, or knot, hold the ends of the strands securely andpermanently but this button also serves as a convenient grip for theuser. The thumb and fingers may be inserted in back of this button ifdesired or they may grip the button as shown in Fig. 5. This button issuch a firm and compact body that it may be used for attachment to ahandle if desired.

It is found that a dust puff made in accordance with this processnaturally forms into an ellipsoidal shape which it continues to retaineven with prolonged use. This shape is of course most convenient for itsintended uses. The kinky strands produced by the knitting are found tointermesh and interlock in such a way that they do not sep arate inhunches and groups even though they are subjected to hard usage anddespite the tendency which cleaning oils have to mat strands of fibrousmaterial together. The kinky shape of the strands also gives this pufiunusual resiliency which makes it more useful in absorbing dust and oiland which increases the utility of the dust pufl. Not only do the kinksin the strands as produced by the previous knitting process give thepuff the characteristics above described but it also provides a muchlarger puff than could be isomer layers, until a desired quantity ofintermeshed layers are formed, bringing opposite sides of the looptogether to bring the strands at that point into close relation with oneanother in cylindrical form and tying the strands in compressedrelation, whereby the looped ends are caused to flare out to form puffs.

2. The method of making dust puffs comprising winding raveled strands ina continuous loop in superimposed intermeshed layers, compressing theloop intermediate its ends, binding the strands together in thecompressed portion at two separated points, and cutting the compressedportion of the loop between the two said points to thereby produce twoindependent puffs each having both ends of its strands firmly securedunder its respective bound portion.

3. A method of making dust puffs comprising winding kinky strands in acontinuous loop in superimposed layers to cause the kinky portions ofadjacent strands to intermesh, bringing opposite sides of the looptogether into a compact cylindrical body and securing them together, andsecuring two portions of each strand in said body and the intermediateportion of each strand being extended from said body in a loop throughthe intermeshed layers.

i. The method of making dust puffs comprising winding kinky raveledstrands into a loop having a plurality of intermeshed resilient layersof kinky strands, compressing together into cylindrical form and tyingin the compressed relation opposing sides of the loop to hold thestrands so tied in a fixed mutual relation, whereby the intermediateporl tions of said strands pufl outwardly from the tied portion in anellipsoidal resilient body.

5. The method of making dust puffs comprising Winding kinky raveledstrands into a loop having a plurality of intermeshed resilient layersof kinky strands, compressing together in cylindrical form and tying inthe compressed relation opposed sides of the loop at spaced points tohold the strands so tied in a fixed mutual relation, whereby theintermediate portions of said strands pufi outward from the tied portionin an ellipsoidal resilient body, and cutting the strands of fibrousmaterial between said spaced points to produce two separate pufis.
